At a very rough level, the only significant mountains are the Cascades. West of the Cascades the climate is very temperate. Warm in the summer, cool in the winter. Occasional heat waves of 90+ degrees for 3-5 days in the summer, occasional cold snaps of less than 32 in the winter.

The sun is harder to describe. Summer it is almost always bright and sunny, rarely rains, can be very dry. Not too many cloudy days. Fall, Winter and Spring are different. We almost never get thunderstorms, but count on variations of mist, drizzle, light and heavy rain from late October to early May. You can go weeks without seeing the sun because of cloud cover, so it is mostly grey with variable amounts of light and moisture.
